In this manner, the space arrangement of the refrigerator is more reasonable, the refrigerator has a larger capacity, the length of the air passage is reduced, the cold loss of the low-temperature airflow generated by the ice-making evaporator 40 is less, the independent ice-making evaporator 40 is used for specially providing the cold for the ice-making chamber, hence the ice-making efficiency of the ice-making machine 30 is improved, the probability that the low-temperature airflow has peculiar smell can be reduced, and the ice-making effect of the ice-making machine 30 is better.

In addition, the blower chamber 12 may be directly defined by the refrigerator cabinet 10 so that the blower 50 is directly installed in the blower chamber 12; alternatively, an installation space of the blower 50 is provided on the refrigerator cabinet 10, a housing of the blower 50 is formed as the blower chamber 12, and the blower 50 is directly installed in the installation space.

It should be noted that the refrigerator door 20 is pivotally connected to the refrigerator cabinet 10, the air inlet 211 is in communication with the air supply port 13 a when the refrigerator door 20 is closed and the air outlet 212 is in communication with the air return port 14 a to provide low-temperature air flow to the ice maker 30; when the refrigerator door 20 is opened, the air inlet 211 is not communicated with the air supply port 13 a and the air outlet 212 is not communicated with the air return port 14 a to stop providing low-temperature air flow to the ice maker 30; furthermore, if the refrigerator is a left-hand refrigerator that opens right-to-left, the blower 50 is correspondingly arranged on the left side wall of the refrigerator to drive the low-temperature air flow to the air inlet 211 from the air supply port 13 a on the left side wall of the refrigerator cabinet 10; if the refrigerator is a right-hand refrigerator that opens left-to-right, the blower 50 is correspondingly installed on the right side wall of the refrigerator to drive the low-temperature air flow to the air inlet 211 from the air supply port 13 a on the right side wall of the refrigerator cabinet 10.

That is to say, the air supply duct 13, the ice-making evaporation chamber 11, the blower chamber 12, the ice-making chamber 21, and the air return duct 14 form an air flow passage, and the air supply duct 13 is positioned above. Therefore, the low-temperature air flow flows into the ice-making chamber 21 from the air supply duct 13, the high-temperature air flow in the ice-making chamber 21 flows back to the ice-making evaporation chamber 11 from the air return port 14 a, and then the position of the air supply duct 13 above enables the low-temperature air flow to quickly flow into the ice-making chamber 21 under the action of gravity and the high-temperature airflow in the ice-making chamber 21 is rapidly drawn back by the blower 50 to accelerate the circulation of the low-temperature airflow, thereby increasing the ice-making speed of the ice maker 30.

In the specific embodiment shown in FIG. 2, the ice-making evaporation chamber 11 is in communication with the blower chamber 12 through a connection chamber (located in a connection section 133 shown in FIG. 13), the front end of the connection chamber is in communication with the rear end of the blower chamber 12, and the rear end of the connection chamber is in communication with the lower part of the ice-making evaporation chamber 11.

Specifically, the lower part of the ice-making evaporation chamber 11 is attached to one end of the connection chamber located at the rear wall of the refrigerator cabinet 10, and one end of the connection chamber located at the side wall of the refrigerator cabinet 10 is in communication with the blower chamber 12 and fastened by screws; furthermore, areas where the connection chamber is connected to the blower chamber 12 and with the ice-making evaporation chamber 11 are sealed by adhesive tape and viscous foam. In this manner, not only can the foaming agent be prevented from entering the chamber to block the airflow passage, but also the air tightness of the airflow passage can be improved, to prevent leakage of low-temperature airflow and improve the ice-making efficiency.

It is to be noted that the connection section 133 having a right angle between the ice-making evaporation chamber 11 and the blower chamber 12, and the connection chamber defined by the connection section 133 allow the low-temperature air flow in the ice-making evaporator 40 to completely flow into the blower chamber 12 through the right-angled connection chamber.

As shown in FIGS. 12 and 13, the refrigerator cabinet 10 includes a cabinet body 15, a first cover plate 16 and a second cover plate 17, wherein the cabinet body 15 includes a casing 151, an inner container 152 and an insulating layer 153 clamped between the casing 151 and the inner container 152, the air supply duct 13, the air return duct 14 and a connection air duct are all embedded in the insulating layer 153, and the rear wall of the cabinet body 15 is provided with a first accommodating groove penetrating through the inner container 152 and part of the insulating layer 153; the first cover plate 16 covers and closes the first accommodating groove and together define the ice-making evaporation chamber 11, a part of the insulating layer 153 of the side wall of the cabinet body 15 protrudes inwards and passes through the inner container 152, a second accommodating groove is defined in the part of the insulating layer 153, the second cover plate 17 covers and closes the second accommodating groove, and the second accommodating groove and the second cover plate together define the blower chamber 12.

Specifically, the insulation layer 153 is arranged between the outer casing 151 and the inner container 152 of the cabinet body 15, part of the insulation layer 153 is hollowed out or the air duct assembly 24 is embedded in the insulation layer 153 to form the air supply air duct 13, the air return duct 14 and the connection air duct; the first accommodating groove is further formed in the rear wall of the cabinet body 15, and the ice-making evaporator 40 is installed in the first accommodating groove; the second accommodating groove is formed in the side wall of the cabinet body 15, the blower 50 is installed in the second accommodating groove, the first cover plate 16 and the rear wall of the casing 151 of the cabinet body 15 are fastened by screws to cover the ice-making evaporator 40, and the second cover plate 17 and the side wall of the casing 151 of the cabinet body 15 are fastened by screws to define the blower chamber 12 together with the second accommodating groove.

In this manner, not only can the arrangement of the blower 50 and the ice-making evaporation chamber 11 on the refrigerator cabinet 10 be more reasonable, so that the refrigerating chamber of the refrigerator has a larger storage space, but also condensation at the ice-making evaporation chamber 11 in the refrigerating chamber can be prevented.

In addition, the bottom of the ice-making evaporation chamber 11 is also provided with a water outlet for discharging condensed water generated during defrosting of the ice-making evaporator 40, and the first cover plate 16 may be provided with an inner plate 161, an outer plate 162 and a cover plate insulating layer 163 (see FIG. 12). Furthermore, by providing the cover plate insulating layer 163, the first cover plate 16 may reduce the loss of the cold of the ice-making evaporation chamber 11 to lower the temperature of the low-temperature airflow entering the ice-making chamber 21, and the ice-making speed of the ice maker 30 is thus increased.

It should be noted that after being installed in the first accommodating groove, the ice-making evaporator 40 is fixed by the first cover plate 16, and the front surface of the first cover plate 16 is flush with the surface of the inner container 152 of the refrigerator cabinet 10, so that the space inside the refrigerating chamber is larger, the blower 50 is installed in the second accommodating groove, and the side wall of the second accommodating groove is made of the same material as the insulating layer 153, so that not only can the blower 50 be fixedly supported, but also leakage of the low-temperature airflow in the blower chamber 12 can be prevented.

With reference to FIGS. 3, 4, 8 and 9, the refrigerator door 20 includes a door body 22, a door cover plate 23 and the air duct assembly 24, wherein the ice-making chamber 21 is defined by the door body 22, an ice storage box 60 is further provided in the ice-making chamber 21, the door cover plate 23 is pivotally connected to the door body 22, the air duct assembly 24 is located in the ice-making chamber 21 and divides the ice-making chamber 21 into an ice-making chamber 21 above for installing the ice maker 30 and an ice storage chamber below for installing the ice storage box 60. The ice maker 30 is installed in the ice-making chamber 21, the ice storage box 60 is installed in the ice storage chamber, the air inlet 211 has an upper branch port 2111 and a lower branch port 2112 which communicate with each other, the upper branch port 2111 is in communication with the ice-making chamber 21, the lower branch port 2112 is in communication with the air duct assembly 24, the air outlet 212 is in communication with the ice storage chamber, and the air duct assembly 24 has an air guide passage 241 that opens at its upper part and a lower air guide port 242 that is in communication with the air guide passage 241 and faces the ice storage chamber.

Specifically, the ice maker 30 is located at the upper part of the ice-making chamber 21 and is fixed to a screw column of a boss on the inner wall of the ice-making chamber 21 by a screw, and a water filling pipe is provided at the upper right inside the ice-making chamber 21 for filling water into the ice maker 30 to make ice, and the air guide passage 241 is located below the ice maker 30, assembled with the ice maker 30 and fixed to the ice maker 30 by the screw column, the right end of the air guide passage 241 is attached to the air inlet 211 of the ice-making chamber 21, so that the low-temperature air flow directly flows into the air guide passage 241, the ice-making efficiency is thus improved; the upper branch port 2111 guides the low-temperature air flow to be blown over the ice-making machine 30, the lower branch port 2112 guides the low-temperature air flow to be blown over the bottom of the ice-making machine 30, and then the low-temperature air flow blown over from the lower part enters the ice storage chamber through the lower air guide port 242 to cool the ice storage box 60 so as to prevent ice stored in the ice storage box 60 from melting; and the ice-making chamber 21 is internally provided with convex ribs, on one hand, to guide the low-temperature air flow, on the other hand, to fixedly support the ice maker 30 and the air guide passage 241.

In this manner, not only can the low-temperature airflow be distributed in the ice-making chamber 21 to improve the ice-making effect of the ice maker 30 and prevent the ice cubes in the ice storage box 60 from melting, but also the connection of the ice maker 30 and the air guide passage 241 becomes more stable to improve the operational stability of the ice maker 30.

As shown in FIGS. 4 and 8, the air guide passage 241 of the air duct assembly 24 is connected between both side walls of the ice-making chamber 21, and one end of the air guide passage 241 is in communication with the lower branch port 2112. Therefore, one end of the air guide passage 241 is in communication with the lower branch port 2112, so that part of the low-temperature air flow can flow into the ice storage box 60 through the lower branch port 2112, thereby preventing ice in the ice storage box 60 from melting and keeping the temperature in the ice storage box 60 constant.

As shown in FIGS. 10 and 11, the door cover plate 23 has a hollow structure, and the side of the door cover plate 23 facing the ice-making chamber 21 is provided with a plurality of bosses. Therefore, the door cover plate 23 with the hollow structure can have a better heat insulation effect without adding a heat insulation material in the door cover plate 23, the refrigerator door 20 is lighter and thinner, the production cost of the refrigerator can be reduced, the processing of the refrigerator door 20 is facilitated, and the refrigerating chamber can have a larger volume so as to store more articles.

In some embodiments, the plurality of bosses have cavities therein, so that the boss also has a good heat insulation effect to further reduce the loss of the cold in the freezing chamber.

In the specific embodiment shown in FIGS. 10 and 11, the plurality of bosses are strip-shaped and include a left boss 231, a top boss 233 and a right boss 232 which are sequentially connected, wherein the left boss 231 is adjacent to the left edge of the door cover plate 23, the top boss 233 is adjacent to the upper edge of the door cover plate 23, and the right boss 232 is adjacent to the right edge of the door cover plate 23. Therefore, the arrangement of the left boss 231, the right boss 232 and the top boss 233 enables the door cover plate 23 to be stronger in the structure, and the door cover plate 23 can be kept in distance from the ice storage box 60 by the left boss 231, the right boss 232 and the top boss 233, avoiding difficulties in opening the door cover plate 23 due to icing, and the door cover plate 23 can be opened more simply and conveniently.

In some embodiments, the cavity of the left boss 231 tapers from left to right and the cavity of the right boss 232 tapers from right to left. Therefore, the structure of the plurality of bosses is more reasonable, and when there are more ice cubes in the ice storage box 60, it is possible to prevent the refrigerator door 20 from being closed due to interference between the bosses and the ice cubes.

As shown in FIG. 7, the air supply duct 13 includes: a first sub air supply section 131 and a second sub air supply section 132, wherein the first sub air supply section 131 and the blower chamber 12 are located in the same side wall, the first sub air supply section 131 gradually inclines downwards from front to back, the air supply port 13 a is formed at the front end of the first sub air supply section 131; the second sub air supply section 132 is located in the rear wall, and the second sub air supply section 132 gradually extends downwards away from the side wall where the blower chamber 12 is located.

That is to say, the first sub air supply section 131 is located on the side wall of the refrigerator cabinet 10, and the second sub air supply section 132 is located on the rear wall of the refrigerator cabinet 10. Therefore, the supply port 13 a and the return port 14 a at the upper end of the side wall of the refrigerator cabinet 10 are communicated with the ice-making evaporation chamber 11 at the lower end of the rear wall of the refrigerator cabinet 10 by providing the first sub supply section 131 and the second sub supply section 132, so that the low-temperature airflow generated by the ice-making evaporator 40 can directly flow out through the supply duct 13.

In some embodiments, the air return duct 14 gradually extends downwards from front to back, and the first sub air supply section 131 and the air return duct 14 gradually move away from each other from front to back. Therefore, the air supply duct 13 is spaced apart from the return duct 14 to reduce heat exchange between the air supply duct 13 and the air flow in the return duct 14, thereby reducing the cold loss of the low-temperature air flow in the air supply duct 13.

With reference to FIG. 7, an air guide groove 18 is provided in each of the air supply duct 13 and the return duct 14. In this manner, not only can the low-temperature air flow be guided by the air guide groove 18 to increase the flow velocity and prevent the air flow from accumulating in the air supply duct 13 or the return duct 14, but also the structural strength of the air supply duct 13 and the return duct 14 is improved.

In some embodiments, the supply air duct 13 and the air return duct 14 are formed by sequentially joining a plurality of air ducts. Specifically, the air supply duct 13 is composed of the first sub air supply section 131, the connection section 133 (with the connection chamber defined therein) and the second sub air supply section 132, and the connection area has adhesive foam and adhesive tapes attached thereto to improve the air tightness of the duct.

Therefore, the air supply duct 13 and the air return duct 14 are divided into a plurality of air ducts to be independently processed, so that the processing of the air supply duct 13 and the air return duct 14 is simpler, and the production cost of the air ducts is reduced.

In the following, an ice-making process of the ice maker 30 of the embodiment of the present disclosure will be described with reference to FIG. 5.

As shown in FIG. 5, the ice-making evaporator 40 is installed on the rear wall of the refrigerator cabinet 10, the ice-making evaporator 40 is in communication with the blower 50 through the air supply duct 13 and the air return duct 14, the blower 50 is installed on the side wall of the refrigerator cabinet 10, the low-temperature air flow in the ice-making evaporator 40 flows into the ice-making chamber 21 through the air supply duct 13, and the high-temperature air flow in the ice-making chamber 21 flows back to the ice-making chamber 21 through the air return duct 14. The ice-making chamber 21 is located on the refrigerator door 20 and is in communication with the air supply air duct 13 through the air inlet 211 and with the air return duct 14 through the air outlet 212, and the ice-making chamber 21 is internally provided with the ice maker 30 and the air guide passage 241 located below the ice maker 30.

Therefore, the ice-making evaporator 40 lowers the temperature of the airflow which then flows into the ice-making chamber 21 through the air supply duct 13 under the driving of the blower 50, part of the air flow supplies cold to the ice-making chamber 21 directly through the upper branch port 2111, and the other part of the air flow directly enters the air duct assembly 24 through the lower branch port 2112 and is distributed by the air guide passage 241, not only supplied to the ice-making machine 30 to make ice, but also supplied to the ice storage box 60 to keep the temperature of the ice storage box 60 constant. In this manner, the high-temperature air flow in the ice-making chamber 21 is drawn away from the ice-making chamber 21 by the blower 50, flows to the ice-making evaporator 40 through the air return duct 14 to be cooled down, and flows to the ice-making chamber 21 again after being cooled down to complete the air flow circulation of the ice maker 30 (the air flow direction is shown by an arrow in FIG. 5).
